In 1861, pasteur conducted his now-famous experiments using flasks with long necks bent into an s-shape. Imagine that you are a scientist working in pasteur’s lab at this time. You decide to tip the flasks so that broth enters the long s-shaped neck. You then return the flask to its upright position. Predict the most likely outcome of tipping one of pasteur’s s-necked flasks.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
